Installing coupling/pipe/bend in a tight space

[nc8861]

I'm replacing a closet bend and a small section of 3" pipe going out to the main stack. My bend currently comes right up against a joist. So I don't really have much clearance on that end - and of course I don't have any clearance on the stack end. I have to cut the current stuff out, install a coupling, section of new pipe, then the bend (the bend has to come up in the same spot). So how do I get the same length/measurements in a space with no clearance? It's not like I can bend the coupling or pipe.

On another board it was suggested that I use a shielded coupling that tightens down with screws. I'd really like to avoid anything but ABS + cement, as I don't want my toilet "stuff" going through a non-cemented joint. Is there any magical way to do this?


Is there any magical way to do this?

Yes Call A Plumber ! ! !

At this point, I like the shielded coupling.

How about a repair coupling?

Get a pipeshredder or rambit and cleanout the hub of the tee on the stack and then repipe.

Is there enough 3" pipe coming out of the tee on the main stack for you to glue on a 45? You might be able to replace that closet bend with two 45s to make a connection to the flange.
